Chicago Bulls guard Derrick Rose will be out approximately eight to 12 months after undergoing surgery to repair his left ACL, said Dr. Brian Cole, who performed the surgery on Saturday.

The 23-year-old Rose tore the ACL on April 28 during the first game of the Bulls' Eastern Conference quarterfinals series against the Philadelphia 76ers. Without Rose, the Bulls became only the fifth No. 1 seed to lose to an eighth seed as the Sixers won in six games.

"Derrick is doing great," Cole said Tuesday at a press conference at Rush University Medical Center. "The surgery went extremely well. Really no surprises. It was pretty routine.

"We're at this point very optimistic. ... We think of recovery as the long process that's in stages. But the short answer is the time frame we believe an athlete of this caliber generally requires is about eight to 12 months. Sometimes shorter, sometimes longer."

That means Rose is likely to miss at least the first two months of next season, or he could miss the entire season.

Bulls general manager Gar Forman said Rose was ready for rehabilitation.

"In the time frame I've spent with him, and I was with him over the weekend, his spirits seemed really good," Forman said. "In his mind, he's determined to attack this rehab and get back to the level that he was at.

"There was a period when he was down. But I think his spirts are good under the circumstances, and I think he's ready to aggressively attack this."

Not likely anytime soon, but in a few years he should be back to a similar level athletically. People can recover from ACL surgery a lot better than they used to. Usually takes till the second year for most guys say they feel like themselves again.

I dunno man. It depends on the tear severity. Sounds to me like he's got a full tear. You just see so many guy who nbever quite seem to have the same pop after these.

Hope you're right though. He does seem like a tough kid, so maybe he can get passed it.
